PARIS – Société Générale, one of the largest French banks, posted a larger fourth-quarter loss on Wednesday than the market had expected and said it would restructure to cut costs and simplify operations.
The bank reported a net loss of 476 million euros ($640 million), compared with a profit of 100 million euros in the period a year earlier. Analysts surveyed by Reuters had expected a net loss of about 237 million euros.
Profit was hurt by a charge of 686 million euros as the bank revalued its own debt, an accounting obligation as the market for those securities improved. It also set aside 300 million euros as a provision against legal costs, and it wrote down 380 million euros of good will in its investment banking business, mostly on the Newedge Group, a brokerage in which it owns a 50 percent stake.
Excluding the one-time items, it said fourth-quarter net income would have been about 537 million euros.
Under Frédéric Oudéa, its chairman and chief executive, Société Générale has been working to emerge from the financial crisis as a leaner institution. It said that from mid-2011 to the end of 2012, it disposed of 16 billion euros of loan portfolio assets from the corporate and investment banking unit, and an additional 19 billion euros of other assets.
The bank’s restructuring, and an improvement in sentiment in the euro zone economy, have helped to restore its market standing. After a difficult 2011 that was marred by questions about Société Générale’s exposure to Greece, the bank’s shares have rallied, gaining 49 percent in the last year.
In a research note to investors, Andrew Lim, a banking analyst at Espirito Santo in London, said that while “management has dealt convincingly with concerns about weak capital adequacy and liquidity in 2012, Société Générale is still struggling to convince investors that it can achieve improved returns.”
Shares in Société Générale, based in Paris, fell 3.5 percent in morning trading on Wednesday.
Société Générale said on Wednesday that Philippe Heim would take over as chief financial officer. Mr. Heim succeeds Bertrand Badré, who is leaving to take a position as managing director for finance at the World Bank. The bank also said Jacques Ripoll, the bank’s asset management chief, “has decided to pursue his career outside the group.”
The restructuring measures announced on Wednesday aim to focus the bank on three core businesses: French retail banking; international retail banking and financial services; and corporate and investment banking and private banking.
The Société Générale group employs about 160,000 employees around the world, and it was not immediately clear if the announcement of a new organization meant the bank would follow the lead of other large global institutions with a round of layoffs.
“There will be review processes to define the target organizations for each entity in the weeks to come,” the bank said. “The organization proposals will be addressed in the framework of an enhanced employee dialogue in keeping with agreements with trade unions and the procedures for consulting with worker councils.”
Mr. Oudéa said in a statement that the purpose of the changes was “to make our organization more efficient and flexible.”
Société Générale said its Tier 1 capital ratio, a measure of the bank’s ability to withstand financial shocks, stood at 10.7 percent at the end of December, up 1.65 percentage points from a year earlier. The French firm said it expected to attain a Core Tier 1 capital target under the accounting rules known as the Basel III regime of 9 percent to 9.5 percent by the end of 2013.
The French bank published its latest results a little more than five years after Jérôme Kerviel, a trader in the bank’s equity derivatives business, built unauthorized positions that led to a 4.9 billion euro loss for Société Générale.
Mr. Kerviel’s conviction on charges of breach of trust and forgery was upheld in October by the Paris Court of Appeals. He also was ordered to serve a three-year prison term, pending appeal, and to repay the bank for the full amount of the 4.9 billion euro loss.
On Tuesday, Mr. Kerviel told the French radio station RTL that he was challenging the repayment order in a labor court, saying he had been ordered to pay without a third-party expert being allowed to study the damages. He added that he was suing Société Générale for an amount equivalent to the 4.9 billion euro trading loss.
